如何在控制器中传递字符串值 [英] How to pass string value in controller

问题描述

我想将字符串值（UserId）从一个控制器传递给http post动作结果（按钮clik）



我尝试过：

I want to pass string value(UserId) from one controller to http post action result(button clik)

What I have tried:

public ActionResult Login(string UserId)
    {
       // string mail = Decrypt(UserId);
        return View();
    }
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Login(UserProfile objUser)
    {

        //string EncryptedID = Decrypt(objUser.UserId);
        if (ModelState.IsValid)
        {
            using (DBEntities db = new DBEntities())
            {
                var obj = db.UserProfiles.Where(a => a.UserName.Equals(objUser.UserName) && a.Password.Equals(objUser.Password)).FirstOrDefault();
                if (obj != null)
                {
                    Session["UserId"] = obj.UserId.ToString();
                    Session["UserName"] = obj.UserName.ToString();
                    return RedirectToAction("UserDashBoard");
                }
            }

推荐答案

您可以与<$ c一起创建锚标记$ c> @ Url.Action 方法，因此当用户点击它时，它会调用登录操作并发布 UserId 价值 IdHere 目前：

You can create a anchor tag in combination with @Url.Action method, so when the user will click it, it will call the Login action and will post the UserId with value IdHere for now:

<a href="@Url.Action("Login","ControllerName", new {UserId = "IdHere"})"

或者您可以使用按钮元素，例如：

or you can use the button element as well like:

<button class="btn btn-info" type="button" id="addressSearch"   

          onclick="location.href='@Url.Action("Login","ControllerName", new {UserId = "IdHere"})'">

希望它能帮助你理解如何处理这个问题。
